An electron in a television tube moves with a speed of 8.23x107 m/s, in a direction perpendicular to the Earth's field, which has a strength of 5.00x10-5 T. You wish to make the electron travel in a straight line by having it pass between two charged parallel plates which are separated by a 6.77 cm distance. What must the potential difference across the plates be in order for the force from the electric field generated by the plates to cancel out the magnetic force?
